Worked: (optional)
Short description of error
check stereoscopy , use cycles to render when the left eye view render done, bleder crash.
Exact steps for others to reproduce the error
Based on a (as simple as possible) attached .blend file with minimum amount of steps
Seems RenderEngine->depsgrah is NULL here getting the evaluated camera.

@Sergey Sharybin (sergey): one for you?
This is caused by the free_blender_memory_if_possible() mechanism.
The best solution would be to sync all view cameras once, then free Blender memory and then render both views in Cycles.
